Corcovado National Park is a highlight of any Costa Rica adventure cruise and well established as one of the country’s prime attractions.

The Golfo Dulce, or “Sweet Gulf”, is well named, given its tranquil bay and rivers lined with mangrove forests speckled with tropical flora, including palms, heliconias, bromeliads, and orchids. Among the flowers hide equally beautiful birds, such as toucans, tanagers, and parrots. Rainforest treks are a must, while the rivers snaking into the jungle are perfect for kayaking, swimming, or paddleboarding. The bay is a prime spot for snorkeling
